Carnarvon is a small town in the Northern Cape Province of South Africa. Carnarvon was established in 1853 on a route between Cape Town and Botswana that was followed by early explorers and traders. It was originally established as a mission station of the Rhenish Missionary Society and named Harmsfontein. The Rhenish missionaries also established Schietfontein to the west, which later developed into a village. In 1874 Harmsfontein was renamed Carnarvon in honour of the British Colonial Secretary, Lord Carnarvon.
